We are still living with the consequences of that today in popular Reformed thinking from the likes of John Piper, R. C. Sproul, and Tim Keller.

What I am trying to argue here [Save Calvinism] and in other works before this one is that the Reformed tradition as I have characterized it is much broader and richer than many of us today imagine. It is not just about "Five Points," and it was never just about [John ] Calvin's thought.

In the twentieth century the Reformed tradition was developed in several ways including additional confessions (Barmen, the Belhar Confession, the 1967 Confession of the PC(USA), and so on). It was also significantly augmented by the work of important thinkers like Karl Barth, T. F. Torrance, Jürgen Moltmann, Emil Brunner, Kathryn Tanner, and so on.

Sometimes we can lose the wood for the trees. Some specific issues dealt with in the book [Saving Calvinism]: the scope of election (who is saved?); the nature of the atonement (do we have to hold to penal substitution if we're Reformed?); the scope of the atonement (for whom did Christ die?); whether we have to hold to some sort of theological determinism (God ordains all that comes to pass).

[ Jonathan] Edwards is the person who really made theological determinism a serious option for Reformed thinkers, and the influence his views had in nineteenth century Reformed thought, in the USA and the UK in particular, is enormous.

For instance, the notion of non-penal substitution. This idea, found in the work of the nineteenth century Scottish Reformed theologian John McLeod Campbell and based upon his reading of the letter to the Hebrews in particular, is that Christ offers up his life and death as a penitential act on our behalf, rather than as a punishment in our stead.

I do think that I have been fortunate to make friendships with other scholars, and form reading groups where ideas are exchanged and papers are read. That is a real boon, and it is something I think every scholar or writer can benefit from.
